Letters Patent No. 106,309, dated August 16, 1870.

IMPROVEMENT IN TOPPLATE OF 'COOKING-STOVES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

scription thereof, reference being had to the acoom panying drawingmaking a part of this specification, in which- 7 Figure l is a plan viewof the lower side of a cro'ss center piece as improved; and

Figures 2 and 3 are vertical cross-sections, respectively, on the linesa: a: and z z of fig. 1.

Letters of like name and kind refer to like parts in each of thefigures.

My invention has for its object the protection of the various partscomposing the top plate of a stove from the intense heat of the fire;and i It consists in lining the whole or a portion of said top platewith any suitable non-conducting substance, as is hereinafter shown anddescribed.

In stoves, as ordinarily constructed, those portions of the top plateimmediately over the'fireare subjected to a much greater degree ottemperature than are, the other parts of the stove,.aud, consequently,are soon burned out and rendered worthless in spite of the additionthereto of ribs, increased thickness, or the use of othersimilarexpedieuts which are resorted to for the purpose of counteracting theefl'ects of the heat and securing increased durability.

To obviate these object-ions I secure to or upon the lower side of :thedifferent portions of the top plate a lining of soapstone, fire-clay,mica, plumbago, or other suitable non-conducting material, which liningreceives the direet action of the fire and protects the iron effectuallyfrom all injury arising therefrom. In order to illustrate my inventionit is only necessary to show its application to one portion of the topplate, as the principle involved would be the same, whether the whole orpart of said plate was protected.

In the annexed drawing- A represents a cross-center of an ordinarycookingstove or range,-provided around its outer lower edge withadownward projecting flange, B, and upon or within its upper side, at itscenter crosswise, with a semicircular depression or groove, 0, which,extending lengthwise of the plate and being provided at itslongitudinahcenter with a transverse bar, '0, serves to' receive andcontain the usual lifter or handle.

Fitted to or within the lower side of the cross-center A, between theflanges B, is a plate or lining ofsuitable non-conducting material, D,which may be secured or anchored to said center by means of the screws Epassing upward through the lining and having their upper ends threadedand fitted into suitable corresponding openings within said center; thehangers or anchors 1* cast into and projecting downward and inward fromsaid center; the bolt G passing downward through said center and liningand having upon its lower end a. nut, g; the staple HI having its endssecured within said center and from thence extending downward and acrosswithin-said lining, by means of suitable dovetailed grooves formedwithin the lower side of said center for the reception of said liningwhen in a plastic state, or by means of any of the many equallyeflicient devicesthat will readily suggest themselves.

It will be seen that when thus applied the lining protects the entirelower surface of the cross-center, with exception of the edge of'theflange 13,, but as the heat received by said flange is quicklytransmitted to and distributed over the upper surface of said center, nopossible injury can result from the exposure of said flange to theaction of the fire.

The advantages possessed by this uon-conducting lining are that, whileaffording complete protection to the portion of the top plate to whichit is applied, so as to render them as durable as any other parts of thestore, its application increases but slightly their original cost, and,in the end, materially reduces the expense of keeping the stove inrepair.

Having thus fully set forth the nature and merits of my invention,

What I claim as new is- Protecting the whole or any portion of the topplate
